RECENT cool weather has brought relief for Queensland Fruit Fly (QFF) control across the region.
Goulburn Murray Valley Regional Fruit Fly Coordinator Ross Abberfield said the current cold snap had already adversely impacted QFF numbers.
Existing fruit fly populations are either searching for food or looking for refuge, rather than breeding.
“Most immature fruit flies will die during winter due to the significant drop in temperature and many adult flies will die in the coming months, however there will be some adults that will survive the winter, which is called overwintering,” Mr Abberfield said.
“These flies are typically newly bred flies from late-ripening fruit that have found themselves in localised warm spots allowing for their survival over winter.”
It is the overwintering QFF population that will be the cause of next season’s fruit fly problems.
Fruit fly numbers identified through the regional trapping program have dropped because of the cooler weather, however there are spots within urban areas that remain suitable for QFF survival throughout the winter so continued awareness and monitoring remains critical.
Protein-based traps and baits are still effective and should be used as they allow for detection of overwintering fruit flies.
Traps should be placed in the morning sun, high in the canopy of evergreen trees in the warmest position in the yard.
“Lemon trees are particularly favoured by QFF to overwinter in and should be carefully monitored,” Mr Abberfield said.
